Standardised, not just "colostrum"
25% immunoglobulin G, stated on the label. Plenty of colostrum products never tell you the IgG fraction, which is the part the research is about.

WHY IT WORKS
Your gut lining is one cell thick.
That single layer decides what gets into your bloodstream and what does not. Colostrum is the substance evolution designed to establish it.
Gut barrier support
Colostrum contains the immunoglobulins and growth factors that establish and maintain the intestinal lining in early life.
The immune system starts in the gut
A large share of immune tissue sits along the intestinal wall, which is why gut barrier support and immune support are the same conversation.
Capsules, no mixing
For people who want the daily habit without a scoop, a shaker and a countertop to wipe down.
The Research
What has been measured in humans.
Colostrum has a real evidence base, most of it in athletes under physical stress. That is a strength and a limitation, and both are below.
-
Barrier
Bovine colostrum reduced the increase in intestinal permeability caused by heavy exercise in healthy volunteers, measured directly by a lactulose-to-rhamnose ratio.
-
Immune
A systematic review of trained and physically active people found bovine colostrum supplementation was associated with improvements in several immune measures, including markers of upper respiratory health.
-
The caveat
A 2021 review of colostrum's constituents and uses notes the field is built on relatively small studies with varied products and doses, so results are promising rather than settled.
Playford RJ, Weiser MJ. Bovine Colostrum: Its Constituents and Uses. Nutrients. 2021.
Simple as 1 · 2 · 3
One capsule, up to three times a day.
1
One capsule with a meal
Start with a single capsule daily alongside food and see how you feel over the first week.
2
Build to three if you want
The label allows one to three capsules a day. Add the second and third gradually rather than starting at the top.
3
Give it a month
Gut lining support is not a same-day sensation. Judge it after four to six weeks of consistent use.
How to Use How to use FIRST
Take one (1) capsule one to three times daily, preferably with meals, or as directed by a healthcare professional. A bottle of 60 capsules is a two-month supply at one a day.
For adults only.
Start low
One capsule a day for the first week. Colostrum is well tolerated by most people, but there is no reason to start at three.
With food
Taking it with a meal is easier on the stomach and fits it naturally into a routine you already have.
Pair it with a probiotic
Colostrum supports the barrier, a probiotic addresses the population living on it. They work on the same problem from different angles.
Powder if you want the studied dose
Most trials used gram-level amounts. Our FIRST powder delivers 2,300 mg per scoop if you want to work at that level.

Easy gut support
Capsules are so much easier for me than powders. I take one with breakfast and stay consistent.

Label sold me
The 25% IgG callout made this feel more serious than the vague colostrum products I had seen.
✓ Verified Buyer
Gentle and simple
I started with one a day. No stomach issues, and my digestion feels more predictable.
✓ Verified Buyer
Good travel product
I keep it in my dopp kit. No scoop, no shaker, no mess.

My gut still reacts to bad choices, but the baseline feels calmer after a month.

Takes consistency
Not something you feel overnight. Around week five I realized I was having fewer off days.

Great with probiotic
I use it with UNBLOAT. The combo has been good for my routine.

Reordered after six weeks
This is one of those products where you notice when your routine gets interrupted.

Good Questions
Everything you might be wondering about FIRST.
What is colostrum? +
It is the milk a mammal produces in the first days after giving birth, before regular milk comes in. It is dense in immunoglobulins, growth factors and other bioactive compounds, and its biological job is to establish the newborn's gut lining and hand over immune protection. Bovine colostrum is the same substance from cows, collected as surplus after the calf has fed.
What does 25% IgG mean? +
Immunoglobulin G is the antibody fraction that most colostrum research focuses on, and 25% is the standardised proportion in this product. It matters because colostrum products vary enormously in IgG content and many never disclose it. At 500 mg per capsule, you are getting about 125 mg of IgG.
Capsules or the powder? +
Capsules for convenience and a daily baseline. The powder if you want the gram-level dose most published trials used — it delivers 2,300 mg of colostrum and 575 mg of IgG per scoop, and mixes into a shake. Athletes and anyone under heavy training load will generally want the powder.
Is it safe if I am lactose intolerant? +
Colostrum is a dairy product and contains lactose, so it is not suitable if you have a milk allergy. Lactose intolerance is different from allergy, and most people who are intolerant handle the small amount in a capsule without trouble. Start with one a day. If you react, stop.
How long before I notice anything? +
Give it four to six weeks. Gut lining support is a gradual process, not a sensation you feel on day two. If nothing has changed after a couple of months of consistent use, the 90-day guarantee is there for exactly that.
Can I take it with a probiotic? +
Yes, and they complement each other. Colostrum supports the barrier itself while a probiotic addresses the bacterial population living on it. Taking both is a reasonable gut stack.
